, is often referred to as the biggest monolith. While the surrounding rocks were eroded, the rock survived as sandstone
making up the surviving Uluru 'monolith'.
monolith is a geological feature consisting of a single massive stone or rock, such as some mountains. For instance, Savandurga mountain is a monolith mountain in India. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano.
In architecture, the term has considerable overlap with
megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces.
The word derives, via the
Latin monolithus, from the Ancient Greek word μονόλιθος ( monólithos), from μόνος ( mónos) meaning "one" or "single" and λίθος ( líthos) meaning "stone".
